Operating Basics

6. Data may be lost if the floppy disk is twisted; bent; or exposed to direct 

sunlight, extreme heat or cold.

7. Do not place heavy objects on your floppy disks.
8. Do not eat, smoke, or use erasers near your floppy disks. Foreign 

particles inside the floppy disk’s jacket can damage the magnetic 

surface.

9. Magnetic energy can destroy the data on your floppy disks. Keep your 

floppy disks away from speakers, radios, television sets and other 

sources of magnetic fields. 

Sound System

Using the microphone

Your computer has two built-in microphones that can be used to record 

monaural sounds into your applications. They can also be used to issue 

voice commands to applications that support such functions.
Since your computer has built-in microphones and speakers, “howling” may 

be heard under certain conditions. Howling occurs when sound from the 

speakers is picked up in the microphones and amplified back to the 

speakers, which amplify it again to the microphones.
This howling occurs repeatedly and causes a very loud, high-pitched noise. 

It is a common phenomenon that occurs in any sound system when 

microphone input is output to a speaker (throughput) and the speaker 

volume is too loud or too close to the microphone. You can control 

throughput by adjusting the volume of your speakers or through the Mute 

function.
To adjust the volume or activate Mute, click start, point to All Programs, 

point to Accessories, point to Entertainment and click Volume Control. 

In the Volume Control panel, you can use the slide bars to adjust the 

volume level or click Mute at the bottom of the panel.

SoundMAX control panel

The SoundMAX control panel lets you control additional functions for the

The Microphone Setup allows you to optimize the microphone input 

settings for your particular configuration. Choose Standard Microphone if 

you have an ordinary desktop microphone. Choose Headset if you have a 

wearable microphone that is positioned directly in front of your mouth.
